Abstract: The characteristics of Digital Signal Processing course are that the theories are abstract，the engineering practices are strong，the students′ performances are uneven. In response to the above characteristics，by using MATLAB GUI tool and combined with FPGA，a comprehensive experiment system was designed based on the integration of demonstration，layering and engineering. The system includes three levels of experiments：verification，application，and engineering training. Taking into account the differences in students′ abilities，the system can meet the needs of students at different levels；it combines abstract algorithms with practical applications to deepen students′ understanding and mastery of theory. Through the completion of FPGA engineering experiments，the engineering practice ability of students can be improved. The practice results showed that the system has assisted the students in mastering the class theoretical knowledge effectively and forming the hardware design thinking；therefore better teaching effect was obtained.
